SPRlNGCAR-STARTER.

SPECIFICATION forming part of Letters Patent No. 293,204,datecl February5, 1884.

' Application filcdhfay24,1$-3. (Kouodch) To all toil/omit may concern:

Be it known that I, IVILLIAM A. IVARRINER, a citizen of the UnitedStates, and a resident of Franklin township, Gloucester county, NewJersey, have invented an Improvement in SpringOar-Starters, of which thefollowing is a specification. A

My invention relates to certain improvements in that class ofcanstarters in which the 1 movement of the axle of the car, when thelatter is stopping, is transmitted to a spring shaft and caused toeffect the winding up ofa spring, the recoil of which is afterwardexerted to start or aid in starting the car.

1 The objects of my invention are to provide noiseless winding and powertransmitting gearing, to readily throw said gearing into and out ofaction, and to control the winding and unwinding of the spring, so as toprevent excess in either direction.

x In the accompanying drawings, Figure '1, Sheet 1, is a longitudinalsection of sufficient of a street-car truck to illustrate my invention;Fig. 2, a transverse section on the line 1 2, Fig. 1; Fig. 3,atransverse section on the line 3 4; Fig. 4, Sheet 2, a plan View ofFig.1; Fig. 5, the same with some of the parts in a different position, andFigs. 6, 7, and 8 (187' tached views 'of parts of the device.

A represents part of the frame or sill of a street-car truck, and B oneof the axles of the same, which is provided with the usual wheels, D,with afixed pinion, E, and with a loose chain-wheel, F. In the rear ofthe axle is a shaft, G, which is adapted near one end to a bearing, a,on the frame, the shaft having a slight play in said bearing, in orderto permit such movement of the opposite end of the shaft as may besufli- 4o cient to carry a spur-wheel, H, thereon into or out'of gearwith the pinionE of the axle. The free. end of the shaft is adapted to abearing, b, on a bar, I, the rear end of which is guided in a hanger, d,on the frame, the front 5 end of the bar being connected to the shortarm of a lever, J, which is hung to a stand, 6, on the platform, thelong arm of the lever being within convenient reach of the driver of thecar. A spring, f, acts upon the bar I and tends to draw the samerearward, so as to free the spur-wheel H from engagement with the pinionE; but by a proper operation of thelever J the bar may be drawn forwardand the wheel H thrown into gear, a catch, 9, on the lever J beingadapted to notches on the stand 6, so as to hold thelever in either ofits extreme positions. An arm, K, is secured at the front end to the barI, and bears at the rear end upon a scroll-cam, h, 011 the shaft G,

said arm having a projecting lug, i,which-can be brought into the pathof a pin, 70, on the 'wheelI-I, in order to stop the rotation of the endof which is hooked, so as to embrace the adapted to engage with acollar, 8, on said 7 axle B, said plate bearing against the hub of adisk, M, on the axle, and having cams w,

axle as the plate is raised. The disk M is held in contact with theplate a at all times by means of a spring, 12, and 011 said disk arepins 1, which pass through openings in the pinion E, and act uponsprings 50, projecting. from pawls 1/, hung to lugs on the face of saidpinion. the outer ends of the pawls being adapted to engage with theface of the chain-wheel F.

On the shaft G is a chain-wheel, N, connected by means of a chain belt,P, to the wheel 8 5 F, and tothe said shaft G is secured one end of acoiled SpringflV, the opposite end of which is secured to some fixedpart of the frame.

The operation of I the device is as follows: WVlien the car is running,the part-s are in the position shown in Figs. 5 and 6, the spring beingunwound or partially unwound, the wheel H out of gear with the pinion E,and any movement of the shaft G, under control of the spring, preventedby the contact of the 5 arm on with the arm K. The latter arm beingfully depressed, the plate a is lowered, as in Fig. 6, and the disk M isthrust by the spring 12 away from the pinion E, thus removing tensionfrom the springs 00, and permitting the'pawls y to remain free fromcontact with the wheel F, so that there is nothing to prevent eitherforward or backward movement of the car. When it is desired to stop thecar, the driver operates the lever J, so as to draw the bar I forwardand hold it in this position, the lever being locked by means of itscatch g. The wheel H is thus brought into gear with the pinion E, andthe shaft G is turned so as to wind up the spring XV. At the same time,under the influence of the scroll-cam h, the rear end of the arm K israised and moved laterally'toward the wheel H, this movement, unless thecar stops in the meantime, being continued until the pin is of the wheelcomes into contact with the lug 1' on the arm and locks said wheel, asshown in Fig. 4. The elevation of the arm K raised the plate a andbrought the cams 10 to bear on the collar 8 of the axle B, as in Fig. 7,the disk M being thereby thrust toward tTlQpllllOl] E, so that the pinst impart tension to the springs 90 and cause the pawls y to bear firmlyagainst the wheel F. \Vhen it is desired to start the car, the lever Jis released, and the bar I is drawn'rearward by means of the spring f,so as to throw the wheel H and pinion E out of gear. The shaft G is nowfree to turn under the influence of the unwinding spring, the movementbeing transmitted, through the me dinm of the wheels N and F, belt I,pawls 7 and'pinion E, to the axle B, which is'caused to turn forward,and thus start the car. As the shaft G turns forward, the rear end ofthe arm K, under control of the scroll-cam h, is moved laterally awayfrom the wheel H until, finally, it comes within the, path of the armin, and thus stops the further movement of the shaft G, as shown in Fig.5. At the same time the end of the arm drops, so as to lower the plate aand its cams and permit the movement of the disk M away from the pinionE, so as to remove the tension from the pawls y and withdraw said pawlsfrom contact with the wheel F, as before.

By properly proportioning the wheels H and N in respect to the pinion Eand wheel F, the power represented by the momentum of the car and storedup by the mechanism described in stopping the car may be applied withgreatly increased effect to the starting of the car. For instance, threeor four turns of the axle B may be made in winding up the spring IV instopping the car, and the power of the spring may be expended ineffecting a single revolution of the axle in starting.

J can be effected more readily than the turn 7 ing of the brake-handle.

I claim as my invention- 1. A spring car-starter in which the axle B,having a chain-wheel, F, and pinion E, with pawl-connection, is combinedwith a spring. shaft, G, having chain-wheel N and spur-wheel H, a belt,I, and means for moving said shaft so as to throw the wheel H into andout of gear with the pinion E, as set forth.

2. The combination of the axle B, the wheel F, the pinion E, and thespring-pawls 11 carried by the pinion and bearing on the wheel, with thespring-shaft, its wheels H and N, and the belt I, as set forth.

3. The combination of the axle B, the wheel F, the pinion E, the pawlsy, hung to said'pinion and having arms 50, and the adjustable disk M,having pins 1, for acting on said arms, as set forth.

4. The combination of the axle B, the wheel F, pinion E, the pawls 7 andtheir arms 00, the disk M and its pins 25, and a cam-plate, n, foradjusting said disk, as set forth.

5. The combination of the axle B, its wheel F and pinion E, thespring-shaft G, its wheel N and spur-wheel H, the belt P, the bar I,carrying one end of said shaft G, the spring f, and the lever J, foracting on said bar I, as specified.

' (i. The combination of the spring-shaft G, having a scroll-cam,'h, andstop-arm m, with the arm K under control of said scroll-cam, as setforth.

7. The combination of the spring-shaft G, having a scroll-cam, 71 andwheel H, with stoppin 7.', with the arm K, controlled by the cam h, andhaving a stop-lug, i, as set forth.

8. The combination of the axle B, the pinion E and its pawls, the diskM, having pins acting on said pawls, the shaft G, having a cam, 71, andthe arm K, controlled by said cam h, and having a cam-plate, a, foractuating th disk M, as set forth. r

In testimony whereof Ihave signed my name to this specification in thepresence of two sub-' scribing witnesses.
